Definitions
- This invention relates to a medical connector according to the precharacterising clause of the principal claim.
- a tubular member or connector which is for example "Y"-shaped, through which a drug can be introduced into that line, is frequently provided.
- a plug of yielding material which can be perforated by the needle of a syringe for introducing a drug into the line is placed on one tubular branch of such connector.
- US 2008/287920 describes a medical connector having the characteristics indicated in the precharacterising part of claim 1.
- This document describes a medical connector having a first rigid body capable of being connected to a medical infusion line; the rigid body has a tubular portion in which there is a conduit which can be closed off at one extremity by a second body of yielding material which is overmoulded onto the first rigid body.
- this second body closes off the extremity of such conduit and is also inserted into the conduit itself. Only a portion of the second body is placed above a corresponding extremity of the tubular portion of the first body .
- the yielding body does not enclose such first body and in use, after the medical connector has been detached from the needle of a syringe or a normal Luer connector, such yielding material may come out of the conduit of the tubular portion or even become detached from it. This could expose a medical operator to contact with the medical product present in the connector, a product which could also be toxic to that operator (such as for example a product used in the treatment of cancer) .
- connection device which can act together with a medical connector without a needle in which such device comprises an axially mobile perforating member.
- US 2008/0093571 describes a device activated by a Luer connector comprising a first body having an internal conduit closed off at one extremity by a second body of yielding material capable of acting together with a male Luer connector. This solution has the same disadvantages as described in connection with US 2008/287920 cited above.
- WO 2008/048777 describes a medical connector activated by a Luer connector and comprising an elongated body with an internal through conduit which is closed off at one extremity by a resilient element within the medical connector .
- the object of this invention is to provide a medical connector which can receive a fluid from a syringe without the latter having to be provided with a needle.
- Another object is to provide an improved medical connector which does not need to be assembled, but which nevertheless comprises two materials, one rigid and one yielding .
- Another object is to provide a medical connector of the type mentioned which has low cost and is simple to use.
- Another object is to provide a medical connector having a plurality of parts connected together in such a way that they are not able to separate and thus form a single-piece body so as to offer high safety during use to medical operators using it, as well as during emergency actions requiring fast times for connecting the connector to the components of a medical infusion line.
- Figure 1 shows a perspective view of a connector according to the invention from a first angle
- Figure 2 shows a view in longitudinal cross-section of two components defining the connector in Figure 1 arranged side by side;
- Figure 3 shows a view in cross-section along the line 3-3 in Figure 1;
- Figure 4 shows a perspective view of the connector in Figure 1 from another angle.
- a medical connector according to the invention is generically indicated by 1.
- This comprises two components or main bodies, 2 and 3, which are made of materials having different rigidities; the first component or body 2 is rigid (for example it is of polycarbonate, ABS, PVC and similar rigid materials), while the second 3 is of a yielding material (such as silicone, TPE or the like) .
- This second body or component is overmoulded onto first body 2 and forms a single piece therewith.
- these bodies are shown side by side in order to aid description.
- First body 2 which is itself of one piece, has a first extremity portion 5, in the form of a cup and arranged around an inner tubular element 7 having a central conduit 8 located along the axis W of the first body.
- An inner wall 9 of cup portion 5 is threaded and is able to act together with a normal male Luer connector of a medical line or other medical device having such a connector (not shown) .
- tubular element 7 continues within an intermediate portion 12 of first body or component 2 and ends in the second extremity portion 14 of aforesaid body 2.
- This second extremity portion 14 is externally threaded and is able to act together with a female Luer connector of a syringe without a needle (not shown), which is in itself known .
- Part 10 of tubular element 7 is of frustoconical shape.
- Central conduit 8 of said element 7 opens at extremities 7A and 7B of the latter which respectively correspond to the first and second portions 5 and 14 of body 2.
- extremities 7A of element 7 is external to first extremity portion 5 of body 2, while second extremity 7B is internal to abovementioned secondary extremity portion 14.
- first extremity portion 5 and intermediate portion 12 there is at least one opening and preferably a plurality of openings 18 opening between a space 19 existing around part 10 of tubular element 7 or between this and the wall of the intermediate portion and extremity portions 12 and 14 of body 2.
- second extremity 7B of the tubular element terminates at a distance D from an opening 20 in second extremity portion 14 of body 2 into which space 19 opens. Through this or such openings the soft material defining the second body is overmoulded onto element 7.
- Second body or component 3 whose shape is illustrated individually in Figure 2, is capable of being overmoulded in space 19 and around intermediate portion 12 of body 2.
- This second component has a first outer portion 22 which can be placed on the outside of second extremity portion 14 and a second portion 23, attached to first portion 22, capable of being located in space 19 above second extremity 7B of tubular element 7, closing off the opening.
- This second portion nevertheless remains within second extremity portion 14 of body 2.
- the connection between first portion 22 and second 23 takes place thanks to the soft and yielding material of second body 3 which penetrates and stops within each opening 18 of body 2.
- This body 3 is therefore a single component (with its portions 22 and 23) enclosing portion 12.
- second portion 23 has an internal cavity 26 opening into its first extremity 26A and closed off at its second extremity 23B.
- cavity 26 has a shape matching that of that element.
- Internal cavity 26 is instead closed off at its other extremity 26B by a yielding extremity part 23A of second portion 23.
- This yielding part 23A can split when a syringe without a needle (but having a usual projecting extremity tubular portion) is connected to the second extremity portion 14 of first body or component 2.
- connector 1 should be connected (as in Figure 1) to a medical line (not shown) through the first extremity portion 5 of first body 2.
- a medical line not shown
- the syringe without a needle is screwed onto second extremity portion 14 of such body 2.
- the normal tubular portion of such syringe "parts" yielding extremity part 23A of second portion 23 and can come into contact with extremity 7B of tubular element 7 connecting to it .
- the displaced yielding part seals against the syringe and the tubular element in contact and allows whatever is present in the syringe (for example medical fluid) to be transferred to the latter.
- the resilience of the yielding part seals off tubular element 7.
- the solution described therefore relates to a medical connector having two components 2 and 3, the first rigid and the second, of soft and yielding material, being overmoulded onto the first body.
- This allows for a syringe without a needle to be used to transfer a fluid in a medical line. Safer use by the part of a user of the syringe, for example a nurse, and even safer insertion of that fluid into the medical line is achieved as a consequence .
- the connector is also of a single piece and is made in such a way as to close off automatically after being connected to a syringe; in addition to this first portion 22 may be shaped with lowered parts 30 to assist attachment of the connector and its connection to the syringe and/or the medical line.
- component 3 encloses first component or body 2 and is stably associated therewith, with the impossibility of second body or component 3 becoming detached from the first. This is due to the presence of the connection between portion 22 and 23 of that second body defined by the material of body 3 placed within each opening 18 of body 2.
